'.[0 ALL WHOM IT- MAY CONCERN:

Be it known that I, THOMAS C. WOODS, of the county oi Marion, uml State of Kentucky, hnJIGiDVEU-Md a new and useful improvement in roilroorl-ccr hrahes ontitlell Thomas (1.,Woods' Improvement in Gar-Brakes," fertile purpose of checking or stopping the train suddenly, if necessary; while under way, when there isrdanger .of collision, or otherwise.

The above improvement consists in so constructing and'erronging the brakes or r rhhers D that'worlc on the face of the wheels, B, thotthey can be used as a common friction-brake, or, when it becomes necessary, they can be dropped down on 'the rails, in front of thcwheels, so that they may pass under the wheels, and

' operate as oohcck or slide, preventing them from turningomrl hence stop the train 02nd I do hereby declare that the following is a full, clear, ond e'xcct description of the construction and operation of the some, reference being hcd to the onnexothdrowings meking part of this'specificotion, llljWl'liGil- Figure 1 is c perspective view of a. common railroad-cor truck, such as are commonly uscrl on rziilroods, showing all the parts or fixtures belonging thereto at one view.

A is the side of the frame of'thc truck, to which the axles of the wheels are attached.

O is tho oroes piccoc of the trnok frame, to which the hrako'fixtures are attached.

4 D is the slide part oi the brake, aml the form of solid broke D, on the friction-side, whore it works against the heel B, and oh the slide-side, which works on the rolls U, is determined by and exactly coincides with theform of the space presented by the rails and wheels. When standing upon the rails, the form or shape of the thi'rdoicle is a mhtter of fancy.

' 0n the nside edge of the ,slidc-side ol' the broke I) there is a hunch, tho earner counterpart of the flanches on tho wheels B, to provontltho cars from jumping thetrocli when the wheels mount the slides or broke.

The above slide or broke Dis need us n. common'friction-hruke under ordinary ciroumstcn'oes,u11d isop'eratcil' in the some manner us those now in use hut in cnsc' of an emergency, when it becomes necessary to stop tho train snddenlyiit is only necessary to detach. the shaft L, which holds up the broke I), from the catch K, and thef drop down on the railsin'front of and pass under tho wheels, and cause them to ride them, and operate as it check or slide, preventing them from turning, and after the train has been stopped, it is-only necessary to'oloso up this slide-broke D, on the face oi tho irhcele B, by turning. the wheel P, as in the ordinary broke, after which baclc the train slightly,-oml the friction on the face of the oheols, when theconnccting rod F is attached to thojbottom of tho'cnr-hody, immediately over-tho contra of the axle R, on ILSKO keep it up as high as tho centre of tho cxle, will raise .up the brakes and rcplhee the shaft L, by'irhich they ore held. up again in the catch K, and ol'tcr which reverse the wheel P, end it rclieres the friction from the face of the wheels, and

l'oc' ee them free toprocood again. I I

L is the ehaft or axle, to which the two slides D are ettacheinnd by which they are held up, and sold rule is made of wrought iron, about two hy tlire'o inches square. V

T is two wrou lit-iron hin e-holts' h nvin on e 0- or sleeve on one end, throu h which the axle hi the r g g 7 E 5' 8 o heels passes, and in whichth'oy rcvolv flnndifrom which all the broke-fixtures are suspended, and working on cold cxle R similar to o hinge, on as to admit of the brakes bcing lowered or roisodat pleasure. Salli hingebolt I also passes through tliechaft L, imfl has oscreir and nntaon the end, .8, in ordor to adjust the brakes -D n'proper dietcnco from the fece oi the wheels, so no not to touch thcm exooptwhen necessary. Said boltT has n collar, neon the middle, at X, in ordorto form a haso, against which the spiral spring W rests.

Scid spring W is for the poirpo'ee of pressing back the hrnkes l'roin the {ace of the wheels 13 when not in use. The above brakes onii fix'turee, when'put together, oonbe raised or low'ered'at pleasure.

The e'leeveon the end of the bolt T, turning on the chic R'of the wheels the some as that of ahin'gc, K,

is the catch which holds up theohaft L, an l i'e attoohedto the frmno oftho truck By a. bolt at the top, 'running sum 2 'lHOS. G. WOODS. Witnesses:
